I used this tune on the XJ13 Chrome Line. I drove it at the Silverstone GP. What a fun, wild ride! Just a bit unstable under hard, high speed braking, but that just adds to the fun of driving this. A little oversteer in the corners, but again, it just adds to the fun of driving. She may be old, but she still knows how to have a wild, good time! Thank you Ghostrider for another great tune!
